Be it-,lrn'own that l, Lao A.. Bursar., a citi-- `.aen of the United State' esiding atCh.e\-'iot, vin the county of Hamilton and State of Ohio, have invented certain new and use ful Improvements in Heating .apparatus9 of which the `follcwine; is a specilieation.

My invention relates `to impimeznents'in jxieating apparatus and radiators therefor.

One of its objects is :to provide an irn proved radiator adapted to he detacha'oly connectedto a heat supply. j

. Another object is to provide improved radiators `adapted to he connected into a system with improved means )to regulate the heat supply' thereto. y

' It further 'consists in certain details of form, combination and arrangement, allot which will be more fullyr slet forth in the de-` v scription of the accompanying dravvings, in

Figure l is a `top plan `View of a heat-generator, a plurality of radiators, and their connections embodying my improvements. Fig. 21s a side elevation or' the same. Fig.

` .lvllyi'improved heating mechaofisn'x is particularly adapted to utilize the exhaust heat from. steam, gas, and. gasolene engines for heating purposes in automobiles and for ein-iilar purposes.

which are composed of metal shells c havin a' closed chamber o.. The shells c are pret-r erably eastin one'piece with openingsfc' c3' in the bottom wall, and openings cl @Givertically abovethe openings@2 c in the top Wall. Cross braces D'adjacent to the openings 02 c." and c3 c are employed to retainthe top and bottom Walls oit' the radiator a uni- `form distance apart. In order to detachably connect the inlet and exit pipes tosaid radiators l provide shells or sleeves E having a flanged head e at one e'nd, which sleeves prefera'ily. closely ptit the openings c2 c4' and 03.05 With the end ofthe sleeve projecting througl'r the openings in the upper WalLof the radiator. f

As shown in Figs. 3, t and .the end of the sleeve projecting through the up )er Wall of the radiator is closed the -li'ormed integral with 'the sleeve, andthe upper end of said sleeve' is threaded to receive a nut F, by ineansof which the sleeve is drawn tightly into place and locke-d upon the packing rings .f f to make a tight joint with the radiator. The end' of the pipe leading to or from the radiator is threaded into the lower end. ci? the sleeve .E The lead e A upper Wall of the radiator is preferahly dished or depressed adjacent to the ings o c5 so that the upperiends ofthe sleeves and the nuts E Willcome practically liuslrufith the main portion of the top.-wall of the radiator.V j Y As shown'iu Fig. 7 the upper end of the sleeve E is open and is threaded on the interior to engage the threads of a metal plugu G, which serves to lock the sleevein place and malo'. a tight joint between the sleeve and the radiator.l .j

In the modification shown inFig. 8 the upper end of the sleeve "E2 is open and threaded upon theiexterior to engage the threads oi? a cap H which serves to lock the 4 e J' L v through. the radiators, or when as the heeft]no4 .medium lntothc I chamber n'iiator C5 trom Whe-nce it is air through the muffler l?, vvitl1-` valve. The valve Fig. 3 may be set with the.L handle below orabove the valve-as desired:v

passed by pipe K- to the radiator C', and thence by a T-connection lc to the pipe B and mutlier b. The casing J of the valve J is provided with a series of notches j which 'are adapted to be successively engaged by a handle L carriedby lthe'valve stem J2, to lock the valve to any. adjusted position. As

shown in Fig. 3 a spring j serves to hold the handle L in engagement with one ofA the notches j except when the handle 1s lifted from said notch by'the operator to shift the for convenient adjustment.

As shown in Fig. 11 the valve handle L is normally held in engagment with a notch in the valve casing by means of a vspring actuated stud 1 seated in av recess iin the end of the valve stem J 3.

As shown in Fig. 12 the valve instead of having a through stem as; shown in Figs. 3 and 9 lis of the shell type and provided with short studs ,or stems J4 cast integral with thevalve shell J 5.

The `outwardly projecting flange m -formed on the radiators is to facilitate the attachment of a wire mat M to the upper and lower faces ofthe radiator to prevent contact of any article which'. might be injured from -direct contact with the radiators.

I am thus enabled'to provide durable and eilicient radiators which can be quickly and conveniently adjusted to position or detached, and with simple and. convenient means for controlling and regulating thecomprising a cast metal one-piece shell having substantially parallel upper and lower walls provided with opposing passages in substantial axial alinement, a' perforated sleeve lextending into an'd connecting alined passages', supply and exit conduits for the' heating medium below the lower wall and connected to separate sleeves, and

'means for locking said sleeves with closed joints to said opposing walls, said means being exposed above the`upper wall to perlopposing. walls, and spacin supporting' the walls against collapsing mit removal of the shell without'aiectiil'g' 'the' connection of sleeve and conduit.'

2. In radiator structures,a radiator 'comy j prs'ing afcast metal ,one-piece shell having substantially `parallel opposing-.walls plie-' vided with opposing passages in'` substantial axial alinement, a perforated sleeve extend-y ing into'and -connectmg alined passages,l

supply andl exit conduits for the heating medium connected to said sleeves, means for locking said sleeves with closed joints to said under the locking pressure of ,the sleeves,

said members Being spaced fromlthesleeves.v

3. In a niechanisin'p,the.. character described, supply` and.' exitmond'uits, a'I cast metal' shell constituting the radiator and having passages through its opposite Walls arranged in pairs, one wall of said sh'ell being depressed in the neighborhood of said passages, perforated sleeves. eachwprovided with a flange at one 'end and threaded atitlfe opposite end, said sleeves being detachablyseated in saidv openings and connected to" said conduits, and means seated externally of members for Said depressedwall and within said dePres-''l sions'for locking said sleeves vwith closedjoints to the opposite walls of said shell, saidl depressions being of a depth at least equal to the thickness of the .securing means, whereby said means Will be retained from projectmg beyond the plane of the outer' l face of the non-depressed portion of 'the wall.

4. In anA apparatus of the character described, a radiator shell having opposing walls, inlet and exit members for the radiator, said members each being removably sup'- ported' in both of the opposing walls, means for removably securing each member in, osition, said means comprising a remova le element positioned on the outer face of one o said Walls, said latter wall having a depression within which said element extends,

the depth ofthe depression being vsuiicient to Y retain the element lfrom projecting outwardly beyond the' normal plane of the outer face of the wall.

In testimony whereof l have aiiixed my signature in presence of two witnesses.
